过剩空气系数与富氧燃烧对理论燃烧温度影响的数值计算

Numerical Calculation about the Affection to the Theoretical Combustion Temperature from the Excess Air Coefficient and Oxygen-enriched Combustion

采用计算流体力学软件FLUENT,对一个圆筒形燃烧器进行仿真,建立数学模型,通过改变边界条件空气流速及空气中含氧量从仿真结果中,得出过剩空气系数和富氧燃烧与理论燃烧温度之间的关系,结果与相关文献的实验数据吻合。

Numerical calculation has became an important means of science, in order to verify the numerical results, using the computational fluid dynamics software FLUENT to establishes the mathematical model of a cylinder-shaped burner, the correct boundary conditions were set up separately in the air speed of flow and the oxygen content of air, and come to the relationship between excess air coefficient,oxygen-enriched combustion and the theoretical combustion temperature, tallies well with the correlation literature empirical datum, thus must use the commercial software numerical computation the merit, enhances the working efficiency, obtains more achievements.
